#161797 - the absolute duration of one timer tick... Responding to: ???'s previous message |
... is dependent on your system clock.
It would be 1 us (hence 50000 timer ticks would cause an overfow after) only on the "classical" 12-clocker 8051 with a 12MHz crystal. You have a single-clocker, and we don't know its clock frequency. You might want to give here a link to the document you mention. Besides, it's the reload registers' (R2CAPH/L) value you are interested in, not the timers' (TH2/TL2). Read the Timer2 tutorial perhaps. http://www.8052.com/tut8052.phtml#TIMER2 JW |
